Featuring an High Performance Computing user: Dr. Dharani

Dr. Dharani Yarrakalva is a researcher with more than 28 publications related to epidemiology. She has experience using Cambridge clusters, and she is currently an Academic General Practitioner and NIHR Clinical Lecturer at Queen Mary University of London. She was receiving one-to-one HPC sessions to use the Apocrita cluster at QMUL, properly.

Dr Dharani uses Stata for exploring her data; she contacted us because her processing took several hours. She was familiar with the use of other clusters in the UK. She has used the Cambridge Service for Data Driven (CSD3) for her research in the past. However, using Apocrita was quite challenging for her during her research at Queen Mary University of London. From my point of view, this might happen because the file systems, and storage are different on each cluster.

We took four sessions throughout September and October 2023 to get familiar with the use of Linux commands in Apocrita, to upload her local files into Apocrita, and to use Stata using the interactive and batch modes to submit HPC jobs.

After the sessions, she was able to run her job in about 13 minutes using 8 cores and 2G. In the past she spent almost 5 hours to complete her job on her laptop. Ticket 34114

You can also request a one-to-one HPC session from our team using Redmine system or you can send an email to ITS-Research

Please bear in mind that if your simulation/processing/research is taking long hours to be computed on your local device. Then, you can contact us to assist you with all the files already set up, and to start with Apocrita and HPC processing at QMUL.
